If it is throwing an 02 sensor code that is where I would start. A GM dealership can tell you exactly which 02 sensor is bad with their analyzer. Unfortunately it is expensive to have them analyze the problem. Don't you just love these electric nightmares we drive?
The EGR valve could be the problem. An analyzer is really the only way to know for sure what is going on otherwise you could end up spending a sizeable amount of money throwing parts at it & still not correct the problem.
